segmentation fault occur while using with v8 and sdl2 #316

Closed colorhook closed 3 years ago

colorhook commented 4 years ago

After using v8 and sdl2 together, segmentation fault occur.

  1. program panic while window render loop
  2. If using headless mode(without sdl2), program is ok.
  3. If disable canvas.draw_xxx method call in window render loop, program is ok too.

then, I found a similar demo and clone the repo: https://github.com/michael-swan/proveit

just add one line code 

extern crate rusty_v8;

and get error

I can reproduce this with Rust nightly, but with two changes I made to the project:

It fails with nearly the same stack trace:

proveit(1373,0x10adb5dc0) malloc: *** error for object 0x200000000000000: pointer being freed was not allocated
proveit(1373,0x10adb5dc0) malloc: *** set a breakpoint in malloc_error_break to debug

and

I would suspect that this is a similar problem like in #299: a mixup of same named functions pulled from different native C / C++ libraries.

Hmm, with SKIA_DEBUG=1 the failure seems to be detected slightly earlier in the constructor of SkSL::Compiler::Compiler:
